I meet the eligibility criteria, now what? 

If you meet the eligibility criteria and would like to be a part of the ABC study, please contact one of our research assistants to schedule a screening visit. 
At this visit you will learn more about ABC and meet with a sleep doctor and bariatric surgeon to understand the two treatment arms and how participating can benefit you!
Participation is entirely voluntary. Whether you participate or not will have no effect on the medical care you receive at either Brigham and Women’s Hospital or Beth Israel Deaconess Medical Center.

Contact info can be found on the ABC brochure.
